Description
One, technical field
The present invention relates to drilling plugging agent, particularly a kind of compressible highly flexible plugging agent.
Two, background technology
Adopt conventional plugging agent leak stopping in the petroleum drilling, generally adopt nut-shell, oyster shell whiting, sheet mica, husk etc., these bridging agents are that petroleum drilling contributes, but exist following shortcoming or deficiency simultaneously: 1. weak effect; 2. the patching materials consumption is big, and plugging time is long; 3. the pump well damage causes the down-hole complex accident; 4. composite application tackles permeability loss, in, in the construction of cracklin and hole formation leakage certain plugging effect is arranged, when running into large-scale leakage, can't solve; 5. the nut-shell rigidity is big, hardness is big, does not have flexiblely, is prone to seal in leakage channel entering place; Can not make the patching materials of big particle diameter get into the leakage channel depths, cause stifled temporarily illusion, cause repeatedly repeating leakage; Cause great financial loss, directly influenced plugging effect and drilling project.
Three, summary of the invention
The purpose of this invention is to provide a kind of compressible highly flexible plugging agent; Irregularly shaped, good snappiness that employing has, compression resilience, the variable combinations of substances of the elasticity of shape under pressure; The shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned existing leak stopping; Improve plugging effect effectively, shorten drilling period, improve drill speed.
Compressible highly flexible plugging agent of the present invention, its composition and content, content are weight part:
Tree elastomer 70-80 SEPIGEL 305 PAM 0.5-1 Polyanionic Cellulose PAC 1.5-3 XC polymer XC 0.5-1 calcium carbonate superfine powder 10-15.
Compound method: above-mentioned substance under the normal temperature and pressure, adds in the tree elastomer with conventional compound method by its component and content successively, and mixing and stirring is treated its drying, and the particulate state that is ground into particle diameter and is 0.05mm-50mm is for use.
Wherein, said tree elastomer is a revertex shape tree elastomer.
The present invention compares with existing bridging agent and has following advantage or beneficial effect:
1, have good snappiness, compression resilience is strong, under pump function, be prone to get into the leakage pore throat and be detained bridge formation.
2, have fine compressibility, can get into the leakage channel depths, improve plugging effect.
3, have irregular deformation property, the easy embedding in the leakage channel of leakage crack, improve the shutoff bearing capacity
4, use range is wide, has the particle diameter shape of different size, adapts to the blocking construction of the large, medium and small crack of hard formation solution cavity type formation leakage especially.
5, have good flexible nature, shape variable under certain temperature and pressure, bridge formation speed is fast, shut-off capacity is strong, has avoided leakage channel caused once more and has destroyed, and is harmless to valve member, can guarantee continuous construction.
6, nontoxic, environmentally safe, operational safety can not cause the down-hole complex accident.
Five, embodiment:
A kind of compressible highly flexible plugging agent, its composition and content, content are weight part:
Compound method: above-mentioned substance by its component and content, under the normal temperature and pressure, is added in the tree elastomer with conventional compound method successively, and mixing and stirring is treated its seasoning or oven dry, and the particulate state that is ground into particle diameter and is 0.05mm-50mm is for use.
Said tree elastomer is a revertex shape tree elastomer.
During use, in plugging drilling fluid, add the 2%-15% of plugging drilling fluid total amount.Provide specific embodiment below:
